More Ed Begley Jr. than Malibu Barbie, eco-friendly dollhouses have endless appeal to pint-sized environmentalists. And after all, why should big kids have all the green home fun?

On the market for a green home with all the eco-friendly bells and whistles like PV panels, rainwater collection systems, and sustainable furnishings. Do you also want this green dream home to have extremely limited square-footage? Today's your lucky day.

Check out these seven remarkable eco-dollhouses — apparently this is the hot new trend in toys — that are made with eco-friendly materials, feature green attributes desirable in real homes, or both. And just like with actual green home shopping, there are considerations of price and aesthetics to take into account: they range from under $40 to over $400 while some are more Frank Lloyd Wright than Fisher Price in design. True, Malibu Barbie's Dream House they ain't, but these seven inspirational homes serve as the ultimate tool in teaching your brood the importance of going green whether your actual home has solar paneling or not. And perhaps after graduating from one of these abodes, you can introduce them to miniature shipping container homes.

My mother was an enthusiastic collector of Fisher Price toys, so naturally, I had the classic FP A-Frame growing up. It looked nothing like this mod take on architect Andrew Gellar's iconic postwar home design. Designed in Sweden, this A-Frame is made from wood fiberboard originating from European forest waste.

If little Eleanor is showing an interest in modern, sustainable architecture than the six-bedroom Emerson House should be right up her alley. It features solar-powered LED lighting and is treated with nontoxic paints and stains.
